IMPROVEMENT IN PADLOCKS.

Specification forming part of Letters kPatent No. 55,167', dated May 29, 1866; antedated May 24, 1866.

To all whom #may concern:

Be it known that I, CYEUs W. SALADEE, of Newark, county of Licking, in the State of Ohio, have invented a new and Improved Mode of Constructing Padlocks; and I hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

The nature of my invention consists, Iii-st, in the peculiar construction and arrangement of a solid sliding lock-bar, A 5 second, in thc novel arrangement for locking both ends of said bar A 5 third, in the peculiar combination of the spring B with the double hook-lever S and lock-bar A; and, fourth, in the arrangement ofthe guides for the sliding ofthe lockbar A.

In the drawings, A is thelock-bar, which is either stamped out of thick iron plate or cast of other suitable metal, the ends ot' which are provided with hooks E and D', into which the corresponding hook ends -ot' the lever S t when locked, as now shown in the drawing.

Under the long end ofthe lock-bar A is graved or stamped into the back ofthe lock a groove, O, (shown by the red dotted lines.) A corresponding stud, D, is next rigidly secured to the under side of the sliding lock-bar A at the point indicated by thered dotted line passing from the stud to the red letter D. This stud D Works freely up and down in the groove O, by which the sliding bar A is kept'in position While slipping' up and down in the lock.

The stud D Will also serve as a stop to prevent the bar A from being pulled entirelyout of the lock.

A lever, S, in form substantially similar to the one shown in the drawing, is next provided, of such length and proportion as to have each end to lock into the notches E and D and firmly hold the lock-bar A down in the lock.

A spring, B, is made to bear against the lever S at any point where it Will have a tendency to press the ends of the lever into the notches E and D.

The center of the lever S is secured in position by the key-stud O, around which the barrel of the key turns in the act of unlocking, the ward of the key striking against a suitable stud, c, on the lever S, so as to turn it and disengage its ends from the notches of the lockbar A. This lever S may be composed of two pieces, each acted upon by a separate spring, and thus made to lock both ends of the sliding bar A in substantially the same manner.

When the lever S, orits equivalent, is thrown out of the notches E and Dl by the key the sliding'bar A is drawn up out of the lock far enough to admit of hooking or unhooking it from the ring or staple to which it is to be attached, and the operation of locking it is simply to press down upon the top of the sliding bar A until the hook ends of the lever S are thrown into the notches E and Dl by the spring B. v

I will here state that the main object I have in view in this invention is to simplify and thereby cheapen the cost of manufacturing a first-class padlock, while at the same time I have endeavored to render the common padlock more durable and less liable to get out of repair. Nothing, I take it, can be conceived of in the Way of a padlock more simple and complete in all its parts than the one here shown.

While it is a double lock, positively locking both ends of the bar A, and self-locking when open, no further complication of working parts is necessary than the one single hook-lever S, or its equivalent, and spring B. The great importance of this is self-evident.

Now, what I claim as new of'my invention, and desire'to secure by Letters Patent, is-

1. The' lever S, or its equivalent, in combi nation with the lock-bar A, in the manner and for the purpose substantially as shown and described.

2. The spring B, or equivalent, iu combination with the lever S and lock-bar A, in the manner and for the purpose substantially as shown and described.
